Title: Exhaust hood of a coke oven battery
Inventor: WYPICH LUCJAN
IPC: C10B33/00
Filed: 1986-03-04
Abstract: The invention can be employed in dust extraction plants of various types of coke oven batteries, in particular those which are highly built-up. The exhaust hood of the coke oven battery is a device which can travel along the battery and works with the passing car from the side of the battery, with the coke or quenching car from below and with the device which deflects the sealing band (tape) which is laid on the suction collector. The object of the exhaust hood of the coke oven battery consists in a leaktight connection to the passing car and the device which deflects the sealing band during removal of the hot dust-laden gas medium emitted upon discharge of the live coke block to the coke or quenching car. The inventive feature is an integrated installation consisting of an exhaust hood lower part which covers the coke car, an exhaust hood upper part which... the coke block during the coke discharge, of a chamber, of a flame breaker whose task is to shorten and dampen any flames produced in the event that the coke residues are not totally removed, and of an inertial chamber which catches all particles with a diameter over 0.25 mm and protects the inner surfaces of the suction collector from excessive wear and from the necessity of having to use significant speeds of the flow of the dust-laden gas medium in this way and of the installed capacity. <IMAGE>

Patent DE-3615874-A1 (DE)
Inventor: HEIZMANN FRIEDER
IPC: B23B49/00
Filed: 1986-05-10
Abstract: A radiation source (10) projects an optical pattern on the surface (17) of the workpiece (18) and the radiation (26) reflected by the surface (17, 22) is reproduced on a radiation receiver (30). Different distances (16, 19) result in different positions of the images (27, 28) of the reproduced surface (17, 22) on a perspective plane (25). The distances (16, 19) are derived from the position of the images (27, 28) by a signal processing device (32). This process is particularly suitable for measuring the depth of drilled holes. A desired depth can be preset with the help of an input means (33). The depth of the drilled hole is continuously measured during the work process and displayed on an optical output means. Once the desired depth is attained, an acoustic signal is given and the driving motor (37) is switched off.

Filed: 1986-12-04
Abstract: The pressure in a continuous high pressure polymerization system, in which ethylene, with or without comonomers, is polymerized under high pressures and temperatures and the unconverted amounts of gas are recycled through the high pressure recycle gas system into the polymerization system, is rapidly reduced to below the particular reaction pressure when predetermined limiting pressure and/or temperature values are exceeded or when other faults occur by opening one or more pressure-relief apparatuses mounted on the high pressure polymerization system and transferring the hot let-down reaction mixture from the polymerization system via one or more let-down lines through one or more separator systems into the atmosphere, by a process in which the high pressure polymerization system is divided into a plurality of isolated sections at the same time as the let-down process is triggered and only the section in which the let-down process is triggered is let down to the atmosphere. Preferably, the sections in which the let-down process is not triggered can be let down into the high pressure recycle gas system, if necessary through a product separator, in synchronization with triggering of the let-down to the atmosphere.
Patent DE-3643128-A1 (DE)
Title: Connected lagging mat
Inventor: SCHAEFER BERND
IPC: E21D11/15
Filed: 1986-12-17
Abstract: Provided for underground roadway lining, in particular profile lining, is a lagging mat having beads which run all the way through on the head sides in each case and are of the same configuration on both sides. The beads are adapted to the respective opening of the channel profile or to the shape of the corresponding lining profile in such a way that the lining profile serves in each case as connection means or complementary coupling element for respectively adjacent lagging mats. In the case of channel profiles, said lining profile is pushed by way of the opening over the bead configured as a triangular bead, so that the beads of the adjacent mats are pushed one into the other and against the rock and are thus effectively held together. Such lagging mats are ergonically advantageous to handle owing to the lack of protruding parts. Moreover, they form a kind of a template by which the lining arches can be mounted or fitted without special measuring work and adaptation. <IMAGE>

Title: Bottom-bracket bearing with sliding-crank drive bearing for bicycles
Inventor: ZIMMERMANN ADOLF
IPC: B62M1/36
Filed: 1987-03-09
Abstract: A bottom-bracket bearing with sliding-crank drive bearing for bicycles makes it possible to cycle with less effort. It is characterised by a drive bearing 5 with sliding crank 4 and control ring 8 installed above the bottom-bracket bearing 1, as can be seen in the drawing. The pedal crank 2 takes up the load and transmits this force via the rod 3, which connects the two cranks to synchronise them, to the sliding crank 4. This sliding crank is guided by the rider 6 over the ring 8, which is mounted off-centre from the drive bearing 5. The ring 8 controls the sliding crank 4 so that its greatest length is reached in the horizontal position. The extended lever arm increases the force, and this force is transmitted from the sliding crank 4 via the sprocket wheel 10 fixed to the drive bearing axle by means of the chain 11 to the sprocket wheel 12, which is fixed to the chain wheel 13 that is mounted movably on the pedal crank axle. Thus the chain wheel 13 transmits the force for riding to the rear wheel via the chain 14. There are no sprocket wheels, chain wheel or chains on the left-hand side of the bicycle. <IMAGE>

Title: Device for removing and burning soot particles present in the exhaust gases from diesel engines
Inventor: ARNOLD WILLI ING GRAD
IPC: F01N3/032
Filed: 1987-12-22
Abstract: A device for removing and burning soot particles present in the exhaust gases from diesel engines has two parallel filter chambers, in each of which a combustion insert is located. The device also has a closure flap, which can be automatically changed over from one end position to the other, for alternate operation of the filter chambers, in such a way that, in one filter chamber closed by the closure flap, the combustion of the soot particles previously deposited therein takes place, while at the same time the other filter chamber, opened by the closure flap and connected to the exhaust gas stream coming from the engine, deals with filtering soot particles out of the exhaust gas stream. The exhaust gas backpressure applying at the inlet of the filter chamber open at the time serves for actuating the closure flap. Furthermore, a first control instrument is provided which interrupts the effect of the exhaust gas backpressure on the closure flap when a predetermined exhaust gas temperature is exceeded. When the exhaust gas backpressure influence is interrupted, the closure flap can automatically be set into a central position, in which both filter chambers are simultaneously connected to the exhaust gas stream. The features described allow an effective automatic change-over of the device in a simple manner, when the latter runs in two-phase operation. Furthermore, however, the device is capable also of ... certain... Original abstract incomplete.

Title: Composition for eliminating body and mouth odour
Inventor: GOETZ HILDEGARD
IPC: A61Q11/00
Filed: 1988-03-09
Abstract: Consumption of garlic or garlic-flavoured food results in an odour nuisance which is very unpleasant, especially for other people, and is caused by effluvium from the body and mouth odour and can be eliminated only inadequately or not at all by previous means such as body hygiene, use of deodorants, oral hygiene, sucking pastilles and the like. The novel composition is intended to eliminate the described odour rapidly, completely and permanently in a very simple and harmless way. The body and mouth odour is eliminated by a mixture, to be taken orally, of melissa and thyme. An outstandingly suitable combination is one of lemon balm (Melissa officinalis) and true thyme (Thymus vulgaris), which are taken, for example, in the form of dried powdered leaves in a mixing ratio of 1:1. Both other species of the two specified herbs and administration in a modification like an extract or mixed with liquids are conceivable. The composition is suitable, by reason of its constituents, as pure natural product for the elimination of unpleasant mouth and body odour caused by garlic virtually without exception for everybody. Adverse side effects appear to be precluded.
